Data Structures
struct	OSPI_DmaFxns
	Driver implementation callbacks. More...
struct	OSPI_DmaConfig
	OSPI DMA Configuration, these are filled by SysCfg based on the DMA driver that is selected. More...

Typedefs
typedef void *	OSPI_DmaHandle
	Handle to the OSPI DMA Config Object returned by OSPI_dmaOpen. More...
typedef int32_t(*	OSPI_dmaOpenFxn) (void *ospiDmaArgs)
	Driver implementation to open a specific DMA driver channel - UDMA, EDMA etc. More...
typedef int32_t(*	OSPI_dmaCloseFxn) (void *ospiDmaArgs)
	Driver implementation to close a specific DMA driver channel - UDMA, EDMA etc. More...
typedef int32_t(*	OSPI_dmaCopyFxn) (void *ospiDmaArgs, void *dst, void *src, uint32_t length, uint32_t timeout)
	Driver implementation to do a DMA copy using a specific DMA driver - UDMA, EDMA etc. More...
typedef int32_t(*	OSPI_dmaItrFxn) (void *ospiDmaArgs)
	Driver implementation to get the interrupt enable status for DMA driver channel. More...

Functions
int32_t	OSPI_dmaOpen (int32_t index)
	API to open an OSPI DMA channel. More...
int32_t	OSPI_dmaClose (OSPI_DmaHandle handle)
